Autor: N Ross Chapman, Reza M Dizaji, R Lynn Kirlin

Publikováno v: Gayana, Vol 68, Iss 2, Pp 108-114 (2004)

Estimation of geoacoustic models of the sea bed is an underlying research issue in understanding acoustic propagation in shallow water environments where the propagation is generally bottom limited. Inversion methods based on matched field processing

Geoacoustic parameter estimation using a back‐wave propagation technique

Autor: N. Ross Chapman, Reza M. Dizaji, R. Lynn Kirlin

Publikováno v: The Journal of the Acoustical Society of America. 106:2133-2133

The concept of back‐wave propagation is developed as an inversion method to estimate ocean geoacoustic parameters where the source location is known. A phase‐regulated technique is introduced to increase the sensitivity of the method for low‐se
